Hi, PS4 user, first time reporting a bug, ran into 2, one right after the other, first got stuck on grind wheel animation near the castle after completing bird in the hand side quest, then reloaded and got stuck in dialog with Berthold after completing the quest
Edit: reloaded without completing bird in the hand quest due to dialog error, and did not encounter bug. Also I approached grind wheel from left side on second attempt, where I approached from right side when I encountered the error
